Bio.  I’m a Research Assistant in Shanghai Jiao Tong University (SJTU). Starting from 2019, I have been in Machine Vision and Intelligence Group under the supervision of Prof. Cewu Lu. Prior to that, I received my M.S degree at the Intelligent Robot Lab in SJTU. My research interests include Computer Vision, Robotic Vision, 3D Vision and Graphics. Currently, I am focusing on modeling and imitating the hand manipulating objects, including 3D hand pose and shape estimation, (hand-held) object reconstruction, and grasp synthesis. I am also interested in NERF and motion synthesis.

Join Us.  I am looking for cooperation and self-motivated interns. Contact me if you are interested in the above topics
